As threatened, Asteroids!

Sorry, you need a browser that supports canvas to play. You should probably upgrade anyway, you're missing out.

Update: You don't need coins, you can press [f] to start. Apparently I should have made that more clear.

Sorry no sounds, shields or extra weapons, there are already other good asteroid games for the HTML5 canvas. I wrote this to try CoffeeScript, which has been quite fun. I posted the source as a gist.

I have some ideas about how I could make it multiplayer which I might consider trying, of course that has been done too.
